  1. Engineering Surveying Civil Engineering & Architecture Unit 4 Site Planning

  2. Historical Surveyors EGYPTIANS SURVEYING FOR TAXATION

  3. Summer Training

  4. GREEK - DIOPTER ROMAN – GROMA Earliest Mapping Tools

  5. In this lesson: • Define Engineering Surveying • Identify Surveying tools included in CEA course • Demonstrate setup of instruments • Demonstrate techniques for finding Elevations and Horizontal Distances • Offer Teaching suggestions

  6. Land Surveyors Commence at the point on intersection of the South right of way line of State Road No.1 and the Eastern boundary line of the Northwest Quarter of Section 31, Township 1 North, Range 1 East, Leon County, Florida, and run North 67 degrees 35 minutes East along said South right of way line of State Road No.1 (Tallahassee and Jacksonville Road) 1565 feet to a point hereinafter called the point of beginning, thence North 67 degrees 35 minutes East along said right of way line of State Road No.1 a distance of 120 feet; thence South 22 degrees 25 minutes East, at right angles to the said South right of way line of State Road No.1 to the North right of way line of S.A.L. Railway, thence Southwesterly along the said Northern line of the S.A.L. Railway right-of-way to a point which is South 22 degrees 25 minutes East at right angles to the said point of beginning, thence in a Northern direction to the point of beginning

  7. Engineering Surveying • Those activities involved in the planning and execution of surveys for the location, design, construction, maintenance and operation of civil and other engineered projects. Journal of Surveying Engineering, American Society of Civil Engineers

  8. Civil Projects

  9. PhiladelphiaRod Telescoping Leveling Rods Leveling Rods

  10. Reading the Rod 3.09 feet 2.90 feet 2.84 feet

  11. Reading the RodYour Turn 4.68 feet 4.49 feet 4.26 feet

  12. Auto Level Transit Total Station Instruments

  13. Tripod

  14. Auto Level

  15. Set up and Stabilize Tripod

  16. Attach Instrument to Tripod

  17. Leveling the Instrument

  18. Sighting the Instrument

  19. Stadia and Crosshairs Top Stadia Bottom Stadia

  20. Surveyor’s Field Notes

  21. Taking Readings Have Assistant hold the rod vertically Focus the Eyepiece Stadia over the Rod Markings Take readings at the Top and the Bottom Stadias and the Crosshair. Record data in Surveyor’s Field Book Top Stadia Bottom Stadia

  22. Terms 1 Benchmark (BM): a permanent, marked point of known elevation Temporary Benchmark (TBM): a semi- permanent point of established elevation used on the specific job Point of Reference (POR): Either the benchmark or the Temporary Benchmark chosen for this job

  23. Terms 2 Turning Point (TP): A point temporarily used to transfer an elevation Backsight (BS): A rod reading taken on a point of elevation (POR) in order to establish the height of the instrument Height of Instrument (HI): The elevation of the line of sight through the level

  24. Terms 3 Foresight (FS): A rod reading taken from a turning point, or a point of reference to an identified point to establish elevation

  25. Approximating Angles

  26. Record Keeping Professional Development Lesson ID Code: 8003

  27. Data Record

  28. Calculating Elevations Mathematical Relationships for Elevation: HI = BS + Elevation at POR Elevation TP 1 = HI - FS

  29. Calculating Elevations

  30. Horizontal Distance Using Stadia ONLY AN APPROXIMATION! Horizontal distance = (Top Stadia – Bottom Stadia) x Stadia Ratio

  31. Horizontal Distance Using Stadia Distance from POR to TP = (8.50-7.92) x 100 = 58 ft Distance from TP to TP1 = (10.77-10.13)x100 = 64 ft

  32. Getting Outside

  33. Curriculum Alignment: • Unit 4 – Site Planning • Lesson 4.5 – Site Grading • Act. 5.4 - Surveying • Autolevel.ppt • SurveyingPictures.ppt
